We all have a little clutter at our front door, often reminding us of things we need to do when we leave the house. IKEA hacker Marlene solved the problem by hacking an IKEA tissue box into mail sorter and posting spot for notes and to-do lists.

This is actually a really clever little device, and all you need to put it together is a Grudtal tissue box, a bit of chalkboard contact paper, and some magnets. Stick the contact paper on one side and affix it to your wall. You can write notes on the chalkboard, pin notes to the box with magnets, and stick any outgoing mail in the tissue slot so you see it when you leave. I like the idea of hanging your keys there, too—I bet you could screw a few hooks into the bottom and make that part of the box, too. Hit the link to see more.
